Resumen : The internet plays a essential role in modern life, but its problematic use, especially involving sexual content, can lead to serious psychosocial issues. Violent pornography is particularly concerning for its potential to desensitize users to aggression and reinforce antisocial behaviors. This study investigated the relationship between violent pornography consumption, problematic sexual internet use, and Dark Tetrad personality traits (Machiavellianism, narcissism, psychopathy, and sadism). A total of 795 participants, mostly female and recruited via social media, completed an online survey measuring these variables. The findings revealed significant associations, with psychopathy and sadism showing the strongest links to problematic sexual use of the internet. Structural equation modeling, controlling for the sex of the participants, confirmed that time spent viewing violent pornography and problematic sexual internet use are associated to the Dark Tetrad traits. These results suggest a reinforcing cycle, where individuals high in psychopathy and sadism are drawn to violent sexual content, which may further entrench these traits and normalize aggressive or antisocial behaviors. The study underscores the importance of addressing the psychological factors behind problematic sexual internet use.

Resumen : Self-report has historically been considered the “gold standard” for personality assessment due to its widespread use. However, its use has been questioned in recent years, especially in contexts such as forensic psychology, due to measurement biases. The purpose of this study was to systematically identify and categorize non-self-report-based instruments used to assess the Dark Tetrad traits or constructs empirically or theoretically associated with them. A systematic review was conducted in PubMed, PsycInfo, Web of Science, and Scopus databases, and 189 studies were included, which reported more than 250 tools. To obtain a joint view of the results, a classification into 6 categories was proposed following Ortner’s and Proyer’s classification and adding two more categories after reviewing the literature, called Objective Personality Measures (OPMs). These results provide authors with a wide range of tools they could include in their studies to obtain more reliable results when dealing with self-report biases because the best assessment will always combine differentmeasurement methods. Therefore, researchers are encouraged to continue using in their studies the non-self-report-based tools collected in this review, to continue designing new ones, and to provide more validity results.

Resumen : Based on the limited validity evidence of Spanish measures for the Dark Tetrad, we validated the Interpersonal Antagonism Scale (IAS), derived from the Short Dark Triad (SD3) and the Assessment of Sadistic Personality (ASP). Study 1 (n = 1132) examined factor structure, internal consistency, and criterion validity, also assessing the combined SD3 + ASP. Study 2 (n = 76) evaluated test–retest reliability, showing good stability. Study 3 (n = 194) assessed construct validity by comparing the IAS with the Short Dark Tetrad. In conclusion, the IAS is a concise, reliable, and valid instrument for measuring antagonistic personality traits.

While the effects of Dark Tetrad traits on aggressive behavior are well-documented, and violent ideation has also been identified as a significant predictor of aggression, research exploring the interrelationships between these factors remains limited. This study aimed to analyze the relationship between Dark Tetrad and reactive and proactive aggression, as well as to examine whether this relationship could be mediated by violent ideation. A sample of 824 Spaniards completed measures of Dark Tetrad, violent ideation, and aggression. Results showed that psychopathy and sadism had the strongest direct effects on both types of aggression, while Machiavellianism and narcissism presented weaker associations. Violent ideation partially mediated these relationships, though the indirect effects were small, indicating that other mechanisms contribute to aggression. In the combined model, which controlled for shared variance among traits, Machiavellianism retained a direct effect only on reactive aggression, while sadism remained a predictor of proactive aggression. In contrast, narcissism lost all predictive power. Proactive and reactive aggression shows distinct underlying motivations. These findings underscore the importance of comprehensively understanding the intrapersonal variables that impact aggression, which facilitates a more accurate approach to identifying risk factors.

This study examines the relations between childhood abuse and Dark Tetrad traits. A cross-sectional retrospective research design was used involving a sample of 372 non-clinical adult participants who completed self-report measures assessing nonviolent and violent parental discipline tactics and the Dark Tetrad traits. Correlations showed that all parental discipline tactics were positively related to Dark Tetrad traits. Regression analyses revealed that psychological aggression uniquely and positively predicted psychopathy and sadism, while severe assault emerged as a unique positive predictor of Machiavellianism, narcissism, and psychopathy. Nonviolent discipline and corporal punishment or minor assault did not make a significant contribution to any of the dark traits. In conclusion, these findings suggest a modest but significant role of an adverse childhood environment in shaping dark personality traits.

Resumen : Increasingly, colleges across the world are contending with rising rates of mental disorders, and in many cases, the demand for services on campus far exceeds the available resources. The present study reports initial results from the first stage of the WHO World Mental Health International College Student project, in which a series of surveys in 19 colleges across eight countries (Australia, Belgium, Germany, Mexico, Northern-Ireland, South-Africa, Spain, United States) were carried out with the aim of estimating prevalence and basic socio-demographic correlates of common mental disorders among first-year college students. Web-based self-report questionnaires administered to incoming first-year students (45.5% pooled response rate) screened for six common lifetime and 12-month DSM-IV mental disorders: major depression, mania/hypomania, generalized anxiety disorder, panic disorder, alcohol use disorder, and substance use disorder. We focus on the 13,984 respondents who were full-time students: 35% of whom screened positive for at least one of the common lifetime disorders assessed and 31% screened positive for at least one 12-month disorder. Syndromes typically had onsets in earlymiddle adolescence and persisted into the year of the survey. Although relatively modest, the strongest correlates of screening positive were older age, female sex, unmarried-deceased parents, no religious affiliation, non-heterosexual identification and behavior, low secondary school ranking, and extrinsic motivation for college enrollment. The weakness of these associations means that the syndromes considered are widely distributed with respect to these variables in the student population. Although the extent to which cost-effective treatment would reduce these risks is unclear, the high level of need for mental health services implied by these results represents a major challenge to institutions of higher education and governments.

We assessed psychometric properties of an online version of the Alcohol Use Disorders Identification Test (AUDIT) among Spanish university students. We used a longitudinal online survey (the UNIVERSAL project) of first-year students (18–24 years old) in five universities, including the AUDIT, as part of the WHO World Mental Health International College Student (WMH-ICS) initiative. A reappraisal interview was carried out with the Timeline Followback (TLFB) for alcohol consumption categories and the Mini International Neuropsychiatric Interview (MINI) for alcohol use disorder. Reliability, construct validity and diagnostic accuracy were assessed. Results: 287 students (75% women) completed the MINI, of whom 242 also completed the TLFB. AUDIT’s Cronbach’s alpha was 0.82. The confirmatory factor analysis for the one-factor solution of the AUDIT showed a good fit to the data. Significant AUDIT score differences were observed by TLFB categories and by MINI disorders. Areas under the curve (AUC) were very large for dependence (AUC = 0.96) and adequate for consumption categories (AUC > 0.7). AUDIT cut-off points of 6/8 (women/men) for moderate-risk drinking and 13 for alcohol dependence showed sensitivity/specificity of 76.2%/78.9% and 56%/97.5%, respectively. The online version of the AUDIT is useful for detecting alcohol consumption categories and alcohol dependence in Spanish university students.

J.; Cebriá, A.; Gabilondo, A.; Gili, M.; Lagares, C.; Piqueras, J. A.; Roca, M.; Rodríguez-Marín, J.; Rodríguez-Jiménez, T.; Soto-Sanz, V.; Vilagut, G.; Alonso, J. Resumen : Background: Research suggests that lesbian, gay and bisexual (LGB) adolescents have a higher risk of suicidal behaviours than their heterosexual peers, but little is known about specific risk factors. Aims: To assess sexual orientation as a risk factor for suicidal behaviours, and to identify other risk factors among LGB adolescents and young adults. Method: A systematic search was made of six databases up to June 2015, including a grey literature search. Population-based longitudinal studies considering non-clinical populations aged 12–26 years and assessing being LGB as a risk factor for suicidal behaviour compared with being heterosexual, or evaluating risk factors for suicidal behaviour within LGB populations, were included. Random effect models were used in meta-analysis. Results: Sexual orientation was significantly associated with suicide attempts in adolescents and youths (OR = 2.26, 95% CI 1.60– 3.20). Gay or bisexual men were more likely to report suicide attempts compared with heterosexual men (OR = 2.21, 95% CI 1.21–4.04). Based on two studies, a non-significant positive association was found between depression and suicide attempts in LGB groups. Conclusions: Sexual orientation is associated with a higher risk of suicide attempt in young people. Further research is needed to assess completed suicide, and specific risk factors affecting the LGB population.

One study tested correlations between traits that may underlie a person-centered profile of “dark EI.”Our study aimed to replicate and extend that research, identifying profiles in Spaniards and examining the differences between the profiles based on different variables of interest. Method: Two studies were designed, the first one (N = 1241) focused on trait EI and the Dark Triad, and the second one expanding the previous (N = 392) focusing on ability EI and the Dark Tetrad. Results: Three profiles were obtained in both studies: nondark and non-EI profile, dark profile, and average narcissistic and high EI profile. The latter showed the highest self-esteem, strengths, well-being, and civic engagement, and the lowest psychological difficulties and personal distress. Conclusions: Our results reinforced the findings of the study we replicated, not supporting the presence of dark EI, but also not supporting the presence of high EI with very low levels of dark traits. These results have implications when designing preventive actions to improve emotional education.

Resumen : Introduction: Suicidal behavior is a significant mental health concern among university students, yet it remains underexplored through a network approach. Traditional methods often overlook the complex interplay of psychological factors influencing suicidal behavior. This study addresses this gap by (a) examining suicidal behavior using network analysis and (b) identifyingthe psychological network of suicidal behavior along with protective and risk factors among university students. Method: The sample consisted of a total of 1048 Spanish university students (M= 20.5 years; SD = 2.5; 58.2% women) from various universities. Several instrumentswere used to measure suicidal behavior, emotional and behavioral difficulties, prosocial behavior, subjective well-being, emotional intelligence, self-esteem, empathy, affect (both positive and negative), and emotional regulation. Data were analyzed using network analysis to understand the relationships among these variables. Results:Atotal of 21.5% of the participants had experienced suicidal thoughts, 26.3% hadwished to be dead or notwake up, 15% had considered specific suicide methods or made plans, and 5.8% had attempted suicide at least once. In addition, 18% had engaged in non-suicidal self-injury (NSSI) at least once.Network analysis revealed that suicidal behaviorwas highly interconnected with other psychological factors, with “considered taking own life” as the most influential node. Key factors included depressive symptoms, positive affect, and emotional intelligence. Suicidal behavior showed a positive connectionwith depressive symptoms and negative affect and a negative connection with self-esteem and positive affect. Stability analysis confirmed the accuracy of the network estimations, indicating reliable insights into the psychological interconnections. Conclusions: These findings indicate that suicidal behavior in university students is a complex, dynamic system shaped by cognitive, emotional, and affective factors. Network analysis, through advanced psychopathological and psychometric models, offers valuable insights into suicidal behavior, improving risk and protective factor assessment. This highlights the need for targeted and comprehensive prevention strategies in educational settings. Tue, 05 May 2026 11:23:35 GMT https://hdl.handle.net/11000/39835 2026-05-05T11:23:35Z
